Know before you buy
If your motherboard does not have built-in M.2 thermal covers, the heatsink model is highly recommended to prevent performance throttling during intense gaming sessions. If your motherboard already includes integrated heatsinks for M.2 slots, you can opt for the version without one to save space and money.
Yes, the WD_BLACK SN850X meets all Sony requirements for PS5 storage expansion. The model with the integrated heatsink is the recommended choice for console use to ensure proper thermal management.
Yes, this drive is backward compatible with PCIe Gen3 slots. However, you will be limited to the maximum speed of the Gen3 interface, meaning you won't reach the full 7300MB/s potential of this Gen4 drive.
Due to the way operating systems calculate storage and the space reserved for drive management, you will see slightly less than the advertised capacity. For example, a 1TB drive will typically show approximately 931GB of usable space in Windows.
The drive performs at its rated speeds natively, but you can download the WD_BLACK Dashboard software to monitor drive health, update firmware, and enable 'Game Mode 2.0,' which helps optimize performance for gaming.
The warranty covers defects in materials and workmanship under normal use for five years from the date of purchase. It does not cover data loss or damage resulting from accidents, abuse, or improper installation.
